Seminiferous Tubules Spermatogenesis

Sertoli cells are regulated by the pituitary hormone known as:

1. FSH

2. GH

3. Prolactin

4. LH

The correct sequence of spermatogenetic stages leading to the formation of sperms in a mature human testis is:

1.	spermatocyte-spermatogonia- spermatid-sperms
2.	spermatogonia-spermatocyte-spermatid-sperms
3.	spermatid-spermatocyte-spermatogonia-sperms
4.	spermatogonia-spermatid-spermatocyte-sperms

Sertoli cells are found in:

1.	ovaries and secrete progesterone
2.	adrenal cortex and secrete adrenaline
3.	seminiferous tubules and provide nutrition to germ cells
4.	pancreas and secrete cholecystokinin

What is the correct sequence of sperm formation?

1.	spermatogonia, spermatocyte, spermatozoa, spermatid
2.	Spermatogonia, spermatozoa, spermatocyte, spermatid
3.	Spermatogonia, spermatocyte, spermatid, spermatozoa
4.	Spermatid, spermatocyte, spermatogonia, spermatozoa

Select the correct option of haploid cells from the following groups :

1.	Primary oocyte, Secondary oocyte, Spermatid
2.	Secondary spermatocyte, First polar body, Ovum
3.	Spermatogonia, Primary spermatocyte, Spermatid
4.	Primary spermatocyte, Secondary spermatocyte, Second polar body

Match the following columns and select the correct option:

	Column-I		Column-II
(a)	Ovary	(i)	Human chorionic gonadotropin
(b)	Placenta	(ii)	Estrogen & Progesterone
(c)	Corpus luteum	(iii)	Androgens
(d)	Leydig cells	(iv)	Progesterone only

Options:	(a)	(b)	(c)	(d)
1.	(iv)	(iii)	(ii)	(i)
2.	(i)	(ii)	(iii)	(iv)
3.	(i)	(iii)	(ii)	(iv)
4.	(ii)	(i)	(iv)	(iii)

Which of the following statements are true for spermatogenesis but do not hold true for Oogenesis?

(a)	It results in the formation of haploid gametes.
(b)	Differentiation of gamete occurs after the completion of meiosis.
(c)	Meiosis occurs continuously in a mitotically dividing stem cell population.
(d)	It is controlled by the Luteinising hormone (LH) and Follicle Stimulating Hormone (FSH) secreted by the anterior pituitary.
(e)	It is initiated at puberty.

Choose the most appropriate answer from the option given below:

1.	(b), (c), and (e) only	2.	(c) and (e) only
3.	(b) and (c) only	4.	(b), (d) and (e) only

Identify the correct option (A), (B), (C), (D) with respect to spermatogenesis. 

1. ICSH, Interstitial cells, Leydig cells, spermiogenesis. 
2. FSH, Sertoli cells, Leydig cells, spermatogenesis. 
3. ICSH, Leydig cells, Sertoli cells, spermatogenesis. 
4. FSH, Leydig cells, Sertoli cells, spermiogenesis
